A Boy with a Bald Spot


8-year-old Al is in for follow-up of an ear infection, but his mother is more interested in why no hair will grow on that spot on the back of his head.

The young boy's ear infection is resolved and he is otherwise quite healthy for his age. The spot has been there since he was born, the mother reports, and hair has never grown there.Any thoughts on what the cause might be? Follow the case in Dr Jon Schneider's slides above and see if your initial hunch is correct.
